will be practically noiseless, which is of simple and novel construction and easily operated.

The machine consists primarily of a casing of suitable construction within which is mounted a cylinder rotatable transversely of the casing, and a. plurality of type-bars arranged and operated so as to form an imprint upon paper carried by said cylinder during the rotation thereof, said cylinder being also capable of longitudinal movement to suitably space the/ lines of type-writing. The operation of the type-writer is effected by the action of suitable motive power contained within the machine. the operation of the keys on the usual key-board being only 'such as may be necessary to release the opcrating means.

I also providev an auxiliary cylinder operated in substantially the same manner as the cylinder above referred to, upon which the original writing can be reproduced in more compactform. v

The many novelties, conveniences and advantages of the various mechanisms employed in my device will more fully appear from the following specifications. due reference being had to the drawings accon'ipanyiiig the same.

1 represents a casing of any suitable construction or material, provided with a main fioor 2, and containing additional floors 8 and 4. On the upper face of the floor 3 is secured a track 5, in which a frame 6 is capable of longitudinal movement. Rotatably mountedin the frame 6 is asquare shaft 7 provided at its outer end with a knob S on the outside of the casing. Slidably supported on the shaft 7 is a'cylinder 9, so as to rotate with said shaft, said cylinder being provided with a segment 10, pivotally connected with arms 11 at the ends of the cylinder. By means of coiled springs12 connecting the segments 10 and arms 11 such segments are held normally in place in said cylinder. At the ends of the segment 10 are finger-plates 13, by means of 'which the segment may be raised for the purpose of insertmg a sheet of paper beneath the same. Upon releasing the segment 10 one edge of the sheet of paper is held firmly thereby, and by rotating the cylinder in the proper direction such paper is caused to encircle the same. in position for use. During this operation the frame 6 and cylinder are withdrawn from the casing 1, and replaced after the sheet of paper is fixed thereon.

t upporte'djon the floor 3 is a circle 14,

provided with a central pivot and connect ing arms 15. each side of the cylinder 9 a series of standards 16, pivotally connected with the.

Mounted on the circle 'l-t on upper ends of which a corresponding series of typc-bars 17. having at their lower ends cams'lS. provided with radial slots 19. in the rear of the standards 16 is a plurality of bars '10 extending downwardly through the floors 3 and l. and capable of limited vertical movement. Each of the bars 20 is provided with a'cli'p 21. carrying a pin 22 adapted to engage one of the slots 19 upon the upward movement of such bar. and cause the movement of the type-bar downwardly to bring the type on the end llO thereof into contact with the paper on the cylinder 9.

Centrally of the bars is a vertical shaft 23 upon which is fixed a cylinder 24 having on its upper part downwardly operating spirals 25, and on the lower part upwardly operating spirals 26, separated by an amin lar channel 27. Pivotally mounted on each of'the bars 20 is a dog28, )rovide'd at its ends with blades 29 and 30, adapted to engage the spirals 25 or 26 as desired, and cause a movement of such dog and the bar to which it is attached in an upward or downward direction, with the result hereinafterset forth.

""In'rear of each of the bars 20 is a sup port 31 to which arepivotal'ly connected cams 32and 33, preferably wedge-shape as shown. In rear of said cams is a leaf spring 3%, centrally attached to the support 31,- whereby said cams are held normally in inward position, or returned thereto. \Vhen in said inward position said cams are adapted to alternately engage the lower end of the dog 28 and the upper end thereof, and exert a force thereon tending to cause an engagement of one or other end of said dog with the cylinder 2 t, and hold the same in such engagement. -At its lower edge the dog is provided with a'pair of notches 35 and 36, adapted to be engaged by the blade 37 of a catch 38 pivoted to the bar 20, and held normally in engagement with the dog 28 by means of an extensile coiled spring 39. Fulcrumed in the frame is a bell-crank lever 10, the short end of which projects upwardly just beneath the inner end of the'catch 38. To the opposite end of the lever 40 is attached a wire 41 which passes through a loop 42 and under a pulley 43 (Fig. 1) to'one of the keys 4% in the keyboard of the machine. Mounted on the shaft 23 so as to cause the rotation thereof is a small electric motor 45, whereby rotation is imparted'to the cylinder 24. When such cylinder is in movement and the key 44 is operated the catch 38 is released, and

the pressure of the cani 33 upon the dog 28 causes an instant engagement of "said dog with the spirals 26. As the cylinder 24: rotates quite rapidly there results from this engagement a quick upward movement of the bar 20. The catch 38 moves upwardly with the barv 20, and when the lower end of the dog 28 swings inwardly the blade 37 of such catch immediately engages the outer 'notch 36, holding the blade 30 in engagement with the spiral 26. Fig. 3. WVhen the bar 20 has been raised to the desired height the blade 37 comes in contact with a trip 46 fixed to the support 31] At this time the cam 32 is exerting a'pressure upon the upper end of the dog 28, causing the blade ,29 thereof to engage one of the spirals 25., u whereupon the bar 20 18 again lowered, carrying the type-bar 17 to its former vertical position. As soon as the blade 37 moves away from. the trip it it is again permitted to enter the notch 35. and the downward movement is continued until the upper engaging end of the dog 28 runs otl the spiral and into the channel 27. The catch 38 is then in position to be acted upon again by the lever 40.

At their upper ends the bars 20 are provided with lugs 47 adapted to engage arms i8 pivotally connected at their outer ends, as at a, and hold such arms normally in horizontal position. The inner ends of the arms e8 are bent downwardly, and carry ink-rolls l9. Near their outer ends the arms 18 are provided with springs 50, the tendency of which is to raise said arms. Upon the upper movement of one of the bars 20 the pressure of the lug 4-7 upon the arm 48 is removed, and such arm immediately raises, causing the ink-roll to pass upwardly over the face of the type on the type-bar 17, and ink th; same immediately preceding the operation of said type-bar, by the continued upward movement of thc bar 20. Upon the return movement of the bar 20 the arm l8 and ink-roll carried there by is again drawn downwardly into its normal position. Near their upper ends the bars 20 pass through openings in an arch shaped guide 51 supported by brackets 52. the inner face of said guide being provided with a pad 53 against which the type-bars l7 strike on their return movement, preventing any sound from such impact.

I prefer to provide one of the bars 20 for a set of three of the type-bars 17, and bring the desired type-bar into position for operation by the bar 20 by shifting the position of the circle 14. For this purpose I prefer to locate said circle so that each of the bars 20 will be normally in rear of the center one of the set of type-bars to be actuated thereby, and bring one or other of the other type-bars in front thereof, as desired. For example, by moving the circle in one direction. capital letters may be produced, and in the opposite direction numerals or other characters.

To accomplish the shifting of the circle 141 provide the following'means, reference being more specially had to the Figs. 6 to 9 inclusive in the drawings: 53 is a bar similar to the bars 20 and capable of vertical movement. Pivoted to the bar 53 is a dog 54, similar to the dog 28, and adapted to be operated by the spirals 25 and 2G. The dog 54 is provided at its lower end with notches 55 and 56 adapted to be engaged by a catch 57 p'ivoted on the bar 53, and held normally in engagement with one or other of said notches by a coiled spring 58. The catch 57 is capable of being released by means of a bell-crank lever 59 upon which intense said catch normally rests. Connected with the lever 59 is a wire 60 passing under a pulley 61 to a key 62 pivoted in the keyboard of the machine. In rear of the dog 54 are spring controlled cams 63 and 64, (shown in broken lines) similar to the cams 32 and 33, and adapted to alternately exert a pressure upon the lower and upper end of the dog 54. Upon the release of the catch 57 the dog 5% engages the spiral 26 at its lower end, and is immediatelycarried upwardly, carrying with it the bar 53. At a 'point above the dog 54 the bar 53 is provided with a plate 65, having-a slot 65, and projecting outwardly from the circle 14 is an arm 66 adapted to enter said slot and be moved laterally thereby upon the upward movement of the .bar 53, the movement of said arm being sufficient to turn the circle 1% enough to bring another set of type-bars in front of the bars 20. Upon the downward movement of thebar 53 the arm 66 and circle 14; are returned to their normal position. To aid in the rotation of the circle 1- guides 67 are provided, fixed to the floor 3 and having openings to permit a free movement of the standards 16 upon the partial rotation of the circle.

W'hen the dog 5% attains the highest point to which the spiral 26 will carry it, it is I retained in that position until the catch 57, which is now in position in the notch 56, as shown in Fig. 8, is released. This is accomplished by means of a trip 68, pivoted to a support 69, and normally held in elevated position by a spring 70. iVhen the dog 5% is at its highest point the inner end of the trip 68 is just above the catch 57, and is drawn downwardly to release the same by means of a wire 71, passing through a loop 72, and to a key in the keyboard similarly to the wire 60. Upon such release the upper end of the dog 54 is forced into engagement with the spiral 25, causing a return movement of the bar 53 downwardly and causing the plate to disengage the arm 66. To move the circle 14 in an opposite direction a bar 72 is provided having a slotted plate 73 actuating an arm 7i projecting outwardly from the circle 14:. The operation of these parts are similar to those of the bar 53 and appurtenant mechanism, but the circle is moved in an, opposite direction thereby.

Atthe inner end of the cylinder 9 is a disk 75, rotatable with saidcylinder and provided with an annular rib 76 adapted to be engaged by a series of teeth 77 supported on the floor 3 in linewith the shaft 7. l pon the rotation of the shaft 7 and disk the rib 76 thereon iswngaged by two of the .-teeth 77, which prevent longitudinal movement of the cylinder 9, and compel the rotapoint the rib 76 has a diagonal wing which enters the next succeeding space between the teeth and causes the disk and cylinder to move longitudinally of the shaft 7 a distanceequal to one of said teeth and spaces. This movement is accomplished at the end of the rotation of the cylinder 9 and at the end of the line printed on the paper thereon, the cylinder being then in position for the printing of the next succeeding line. The rib T6 is also provided with a wing T9 oppositely disposed to the wing 78, whereby by reversing the rotation of the cylinder 3) the longiudinal movement thereof is also reversed.

Pivoted on the floor it as at b is a lever 80. the inner end of which is formed into a circle 81, of substantially the same diameter as the cylinder 2%. The bars 20 are provided at a point below the circle 81 with inwardly projecting pins 82, which engage such circle when the bars 20 have nearly reached th end of their upward strokes and raise said circle a slight distance. The rear end of the lever is correspondingly lowered, carrying with it a shift-bar 83 in the rear end of the machine. On the upper end of the bar 83 is a frame 84:, carrying a spring-controlled dog S5.adapted to engage the teeth of a ratchet-wheel 8G rotatably mounted above floor 3 conveniently to the bar 83. The dog 85 is held normally out of engagement with the wheel 86 by means of a lug S8 in engagement with a projection 89 on said dog. Upon the downward movement of the bar 83 such dog is permitted to move inwardly into engagement with one of the teeth of said wheel, anda return movement of the bar 83, induced by a spring 87, causes said dog to.rotate the wheel 86 the distance of one of said teeth, whereupon said dog is again thrown outwardly. out of engagement with said wheel.

The wheel 86 is centrally provided with a square opening 89 which receives the inner end of the shaft 7 when the frame (3 is fully inserted in the machine, whereby said shaft T and the cylinder 0 are caused to rotate with the wheel 86. The spacing of the letters in the line is thus provided for, the distance between said letters being determined by the spacing of the teeth upon the wheel 86. In rear of the wheel 86 and rotatable therewith is a toothed disk 90, engaged by a springtooth 91. which acts as a drag upon the wheel 86. The notches in the disk 90 (Ul1espond with those in the wheel'oh, so that as said wheel completes one of its movements the tooth 91 in position to prevent further rotation thereof, holding the same from accidental movement. To a key 92 in the ke v key 92 the shift-bar 83 can be actuated, causing a spacing of the letters upon the cylinder 9.

In the front of the casing 1 is an inclined portion 96 provided with a glass 97 through which the cylinder 9 may be observed at a point where the Writing is being produced thereon. In the rear of the casing is suspended a small electric light 98, by means of which sutlicient light can be provided for the interior of the case. The opening to the part inclosing the cylinder 9 is prefer ably closed by small sliding doors 99, which come together just in rear of the knob 8.

To recapitulate, the completed operation of the machine is as follows: The frame (3 is withdrawn from the machine with the cylinder 9 in place therein. A sheet of paper is then secured in place on such cylinder and the frame returned to its former position in the machine, with the shaft 7 in engagement with the ratchet-Wheel 86. The cylinder 9 is in position with the segment 1 0 near the top thereof so as to leave such space for margin as may be desired. The motorAlS being in operation, and the cylinder 24 in constant rotation, the desired key in the keyboard is touched by the finger of the operator, a slight touch being sufficientto cause the release of one of the catches 3S. and corresponding movement of the bar 20 to which it is attached. The desired type-bar is thereby actuated and returned to its normal position. the type being inked both before and after such operation. If it is desired to change the position of the type-bars before the printing: operation, this is accomplished by touching; the proper key for shifting the circle 14. The arrangement of the key-board and operation thereof may be similar to that in other machines. exceptthat very little pressul'c upon the keys is required by reason of the main part of the operation being performed by power.

In the lower part of the machine is slidably mounted a frame 100 similar to the frame (3. and carrying a square shaft 101.

upon which is mounted a cylinder 102 so as to rotate therewith. Said cylinder is provided with a segment 103 by means of which a sheet of paper may be secured thereon. The end of the shaft 101 enters a. square opening in a ratchet-wheel 10-1 rotatably mounted in the rear of the casino 1 con venientlyto the shift-bar and adapted to be operated therefrom by means of a frame 105 on the lower end of said bar. carrying a sprimacontrolled dog 106 of similar construction and operation to the dog 85. Each movement of the bar 93 gives to the wheel 10% and cylinder 10?. a rotating nm'ement.equal to one of the teeth of said wheel. Integral with-the cylinder 102 is a. die 107 provided with an annular rib 108 engaged by teeth 109 onthe door of the machine and similarly constructed to the rib 76. On each side of the cylinder 102 is u series of standards 110 upon which are pivotally mounted type-bars 111, similar in arrangement to the type-bars 1?, and adapted to be actuated in the same manner and at the same time by the bars 20. The type-bars 111 are also provided with ink rolls 112 carried by arms 113 constructed and operated in a similar manner to those in the upper part of the machine. The operation of the mechanical parts in the lower part of the machine by means of which printing may be effected upon the cylinder 102 being identical with those which perform the same work on the cylinder 0. no further illustration or description thereof is deemed necessary.

By forming the cylinder 102 with a considerably larger diameter than that of the cylinder 9, the printed matter on the latter cylinder can not only be duplicated upon the larger cylinder, but several lines on the sheet on the small cylinder can be copied on one line on the larger cylinder. and the writing on the larger cylinder can be condensed still further by decreasing the amount of spacing between the letters in the lines. and also between the lines. By this means SOY- eral letters which are written on the small cylinder may be copied on one sheet on the larger cylinder for filing purposes. and will occupy a great deal less space when thus reproduced than is required by the copying method now employed.

All the parts of the machine are constructed with a view to the silent operation thereof. and by reason of all of the working: parts beinginclosed within a casing. the sound is mull'led. and the operation of the machine practically noiseless. so as not to interfere with conversation in the vicinity ol the machine. This will he reconnimrd as a great advantage in cases where testimony i being taken directly upon the machine. and in other uses where the noise of tho machin might interfere with the dictation. or with a perfect umlcrstandin; of slnlciiicnts made to the operator while the machine is in action.

ll will be obvious that many changes a be made in the inechauiyal s1 ructures whi -u are embodied in my machine. and in the on oration thereof. without departing from th spirit of the invention. and 1 do not wish to be understood as limiting: myself to the particular construction. arramnunciu or open ation of parts as shown and set forth herein.
